The attached video demonstrates various advanced editing techniques. I used a rolling edit to edit two clips. A rolling edit is when one clip is made shorter while the second clip is made longer by the same amount, or vice versa. The main purpose of a rolling edit is to trim or lengthen clips without adding length to the video. Additionally, I used multiple keyboard shortcuts to trim video clips. The keyboard edits were tough to remember at first. After getting used to them, they became easier to use.
